Referring now to FIG. 1, aspects of an illustrative operatingenvironment 100 for various concepts disclosed herein will be described.It should be understood that the operating environment 100 and thevarious components thereof have been greatly simplified for purposes ofdiscussion. Accordingly, additional or alternative components of theoperating environment 100 can be made available without departing fromthe embodiments described herein.

The operating environment 100 shown in FIG. 1 includes a mobile device102 that is configured to connect to and communicate with one or moreradio access networks (“RANs”) for voice and/or data communicationsbetween the mobile device 102 and one or more other mobile devices,computers, servers, networking devices, and/or other networks (notshown). The mobile device 102 is also configured to receive a cellbroadcast message 104 from one or more RANs. The cell broadcast message104 can include information regarding network signaling load conditionsof one or more RANs to which the mobile device 102 is capable ofconnecting. The mobile device 102 can select one or more RANs to connectto, based at least in part upon the signaling load information includedin the cell broadcast message 104.

In the illustrated example, the mobile device 102 receives the cellbroadcast message 104 including local signaling load information 106collected by a base station 108 that is operating within a cell 110 of aRAN. As used herein, a “signaling load” refers to a load created by oneor more signaling operations between one or more of RANs and the mobiledevice 102 via one or more signaling bearers. Moreover, a “singlingload” specifically excludes any traffic load associated with one or moretraffic bearers. For example, an LTE RAN base station can monitor andreport the utilization of physical uplink and downlink control channels(“PUCCH” and “PDCCH”) according to the percentage of time theseresources are idle and available over a specified time interval.

As used herein, a “cell” refers to a geographical area that is served byone or more base stations operating within a RAN. As used herein, a“base station” refers to a radio receiver and/or transmitter(collectively, transceiver) that is/are configured to provide aradio/air interface by which one or more mobile devices, such as themobile device 102, can connect to a network. Accordingly, a base stationis intended to encompass one or more base transceiver stations (“BTSs”),one or more Node Bs, one or more eNodeBs, and/or other networking nodesthat are capable of providing a radio/air interface regardless of thetechnologies utilized to do so. A base station can be in communicationwith one or more antennas (not shown), each of which may be configuredin accordance with any antenna design specifications to provide aphysical interface for receiving and transmitting radio waves to/from anetwork.

The cell broadcast message 104 can additionally or alternatively includeat least a portion of signaling load information 112A-112N (hereinafter,at times, referred to collectively or generically as “signaling loadinformation 112”) collected by one or more other base stations 114A-114N(hereinafter, at times, referred to collectively or generically as“other base stations 114”) that operate in corresponding cells 116A-116N(hereinafter, at times, referred to collectively or generically as“other cells 116”) of the same RAN as the cell 110 or one or more otherRANs. In some instances, the base station 108 operates utilizing a firstfrequency of a radio access technology (“RAT”), while one or more of theother base stations 114 operate utilizing a second frequency of the sameRAT. As used herein, a RAT can refer to any mobile telecommunicationsstandard or draft standard thereof, or any other technology by which amobile device, such as the mobile device 102, can wirelessly access aRAN.

The mobile device 102 may be a cellular phone, a feature phone, asmartphone, a mobile computing device, a tablet computing device, aportable television, a portable video game console, or any othercomputing device that is configured to connect to and communicate withone or more RANs via one or more radio access components. In someembodiments, the mobile device 102 includes an integrated or externalradio access component that facilitates wireless communication with oneor more RANs. The radio access component may be a cellular telephonethat is in wired or wireless communication with the mobile device 102 tofacilitate a tethered data connection to one or more RANs.Alternatively, the access component includes a wireless transceiverconfigured to send data to and receive data from one or more RANs and auniversal serial bus (“USB”) or another communication interface forconnection to the mobile device 102 so as to enable tethering. In anycase, the mobile device 102 can wirelessly communicate with one or moreRANs over a radio/air interface in accordance with one or more RATs. Themobile device 102 may also initiate, receive, and/or maintain voicecalls with one or more other voice-enabled telecommunications devicessuch as other mobile devices or landline devices (not shown). The mobiledevice 102 may also exchange Short Message Service (“SMS”) messages,Multimedia Message Service (“MMS”) messages, email, and/or othermessages with other devices (not shown).

The cell broadcast message 104 can include any message that is capableof being sent to the mobile device 102 from a base station over aradio/air interface. The cell broadcast message 104 can be sent to themobile device 102 using any physical, transport, and/or logicalchannels. These channel types are generally known and therefore are notdescribed in greater detail herein.

In some embodiments, the cell broadcast message 104 is or includes aSystem Information Block (“SIB”). In some other embodiments, the cellbroadcast message 104 is included in a SIB that contains otherinformation. The SIB may be a new SIB configured to include signalingload information such as the local signaling load information 106 and/orthe signaling load information 112. Alternatively, the SIB may be anexisting SIB that has been modified to include signaling loadinformation.

In some embodiments, the cell broadcast message 104 is an SMS message.In these embodiments, the base station 108 can send the cell broadcastmessage 104 to the mobile device 102, and potentially to one or moreother mobile devices that are connected to the base station 108 orotherwise operating within the cell 110, via SMS Cell Broadcast(“SMS-CB”). Alternatively, in these embodiments, the base station 108can send the cell broadcast message 104 to the mobile device 102 via SMSPeer-to-Peer (“SMPP”). The cell broadcast message 104 may be sent to themobile device 102 via other messaging services including, but notlimited to, MMS, Wireless Application Protocol (“WAP”) push message,Unstructured Supplementary Service Data (“USSD”), or any combinationthereof. It should be understood that network elements, such as ShortMessage Service Centers (“SMSCs”), Multimedia Message Service Centers(“MMSCs”), WAP servers, USSD servers, and the like, that support theaforementioned messaging services are not illustrated merely for ease ofdescription, however, these and/or other network elements can beutilized to support the aforementioned delivery methods of the cellbroadcast message 104.

In the illustrated example, the mobile device 102 receives the cellbroadcast message 104 from the base station 108. Alternatively oradditionally, the mobile device 102 can receive one or more cellbroadcast messages from any number of base stations such as one or moreof the other base stations 114. Also in the illustrated example, thecell broadcast message 104 includes the local signaling load information106 and the signaling load information 112. It is contemplated, however,that the cell broadcast message 104 may include only the local signalingload information 106, only the signaling load information 112A, only thesignaling load information 112B, only the signaling load information112N, or any combination thereof.

The mobile device 102 includes an operating system 118, a networkconnection manager 120, a network decision engine 122, and one or moreradio access components 124. The operating system 118 is a program forcontrolling the operation of the mobile device 102. The operating system118 can include a member of the SYMBIAN OS family of operating systemsfrom SYMBIAN LIMITED, a member of the WINDOWS MOBILE OS and/or WINDOWSPHONE OS families of operating systems from MICROSOFT CORPORATION, amember of the PALM WEBOS family of operating systems from HEWLETTPACKARD CORPORATION, a member of the BLACKBERRY OS family of operatingsystems from RESEARCH IN MOTION LIMITED, a member of the IOS family ofoperating systems from APPLE INC., a member of the ANDROID OS family ofoperating systems from GOOGLE INC., and/or other operating systems.These operating systems are merely illustrative of some contemplatedoperating systems that may be used in accordance with variousembodiments of the concepts and technologies described herein andtherefore should not be construed as being limiting in any way.

The network connection manager 120 can be configured to manage all or aportion of the network connections available to the mobile device 102 ata given time, including, for example, connections established via one ormore radios of the mobile device 102 such as one or more of the radioaccess components 124. In some embodiments, the network connectionmanager 120 is included as part of the operating system 118 and/oranother application stored on the mobile device 102 such as the networkdecision engine 122.

The network decision engine 122 utilizes network signaling loadinformation included in cell broadcast messages, such as the cellbroadcast message 104, to determine to which network the mobile device102 should connect. In some embodiments, the network decision engine 122is an application program that includes computer-executable instructionsthat, when executed by one or more processors of the mobile device 102,cause the mobile device 102 to analyze the network signaling loadinformation included in one or more cell broadcast messages to selectone or more RANs and instruct the mobile device 102, and moreparticularly, the network connection manager 120, to connect to theselected RAN(s).

In some embodiments, the local signaling load information 106 and/or thesignaling load information 112 includes historic network signaling loadinformation. As used herein, “historic network signaling loadinformation” can include signaling load information obtained based uponnetwork signaling load experienced by the base station 108 and/or one ormore of the other base stations 114 in the past or otherwise innon-real-time. In some embodiments, historic network signaling loadinformation is utilized by the mobile device 102 to identify one or morenetwork signaling load trends over a specified period of time. Thistrending network signaling load information can be useful to the mobiledevice 102 to predict times during which network signaling load isfavorable or not to support communications between the mobile device 102and one or more RANs.

In some other embodiments, the local signaling load information 106and/or the signaling load information 112 includes current networksignaling load information. As used herein, “current network signalingload data” can include network signaling load data that is obtainedbased upon a network signaling load experienced by the base station 108and/or one or more of the other base stations 114 in real-time or nearreal-time. Real-time, in this context, is the actual time during which anetwork signaling load is experienced by the base station 108 and/or oneor more of the other base stations 114. Near real-time, in this context,is the actual time during which a network signaling load is experiencedby the base station 108 and/or one or more of the other base stations114 plus a delay on the order of seconds, minutes, or any order ofmagnitude thereof, for example.

What constitutes near-real time network signaling load informationversus historic network signaling load information can be defined by aservice provider that provides service via the base station 108 and/orone or more of the other base stations 114. It should be understood thatreal-time network signaling load information associated with a real-timenetwork signaling load of the base station 108 and/or one or more of theother base stations 114, and near real-time network signaling loadinformation associated with a near real-time network signaling load ofthe base station 108 and/or one or more of the other base stations 114might be received by the mobile device 102 with delay caused by latencyand/or other network phenomena. Moreover, this delay may increase withthe additional time needed to generate the cell broadcast message 104including the local signaling load information 106 and/or the signalingload information 112, and to send the cell broadcast message 104 to themobile device 102.

In some embodiments, the network decision engine 122 utilizes additionalinformation to select one or more RANs. This information can include,but is not limited to, one or more policies and/or one or more userprofiles. As used herein, the term “policy” refers to one or moresettings, one or more configurations, one or more rules, and/or the likethat define, at least in part, one or more courses or methods of actionin light of one or more conditions to be used in a determination made bythe mobile device 102 regarding to which RAN(s) the mobile device 102should connect. In some embodiments, a policy includes one or more rulesthat specify one or more if-then conditions by which to handle aparticular situation, such as redirecting network traffic based uponnetwork signaling load experienced by the base station 108 and/or one ormore of the other base stations 114 and that is reported to the mobiledevice 102 in the cell broadcast message 104. In some other embodiments,a policy includes one or more matrices of cause and effect conditions,tables of actions, and/or the like for responding to or otherwisedealing with certain stimuli, such as network conditions evidenced bythe local signaling load information 106, the signaling load information112, and/or other stimuli.

As used herein, the term “user profile” refers to a collection of dataassociated with a user that accesses one or more RANs via a device suchas the mobile device 102. A user in this context refers to an individualor other entity. A user profile can define information regarding aservice agreement between a user and one or more service providers thatprovide a service, at least in part, via one or more RANs. The serviceagreement may include terms of service for pre-paid and/or post-paidservice. The service agreement may include terms of roaming agreementsbetween two or more service providers such as mobile telecommunicationscarriers. The service agreement may define a service tier for the user.A service tier may establish a priority for a user in regard toutilizing network resources to connect to one or more RANs via themobile device 102.

The WWAN can utilize oneor more mobile telecommunications technologies, such as those describedabove, to provide voice and/or data services via one or more RANs to oneor more radio components of one or more mobile devices, such as theradio access component(s) 124 of mobile device 102. Moreover, a mobiletelecommunications network can provide a connection to an internet orother WAN so that the mobile device 102 can access internet content suchas websites, streaming media, online video games, downloadable content,and the like.

As mentioned above, the cell 110 and the other cells 116 may be part ofthe same RAN or any number of different RANs. In some instances, themobile device 102 is capable of simultaneous connection to the cell 110in addition to one or more of the other cells 116.

Turning now to FIG. 2, a flow diagram illustrating aspects of a method200 for generating a cell broadcast message, such as the cell broadcastmessage 104, that includes network signaling load information will bedescribed, according to an illustrative embodiment. It should beunderstood that the operations of the illustrative methods disclosedherein are not necessarily presented in any particular order and thatperformance of some or all of the operations in an alternative order(s)is possible and is contemplated. The operations have been presented inthe demonstrated order for ease of description and illustration.Operations may be combined, separated, added, omitted, modified, and/orperformed simultaneously or in another order without departing from thescope of the subject disclosure.

It also should be understood that the illustrated methods can be endedat any time and need not be performed in their entirety. Some or alloperations of the methods, and/or substantially equivalent operations,can be performed by execution of computer-executable instructionsincluded on a computer-readable storage media, as defined below. Theterm “computer-executable instructions,” and variants thereof, as usedin the description and claims, is used expansively herein to includeroutines, application programs, software, application modules, programmodules, components, data structures, algorithms, and the like.Computer-executable instructions can be implemented on various systemconfigurations, including single-processor or multiprocessor systems,distributed computing systems, minicomputers, mainframe computers,personal computers, hand-held computing devices, microprocessor-based,programmable consumer electronics, combinations thereof, and the like.

Thus, it should be appreciated that the logical operations describedherein may be implemented (1) as a sequence of computer implemented actsor program modules running on a computing system and/or (2) asinterconnected machine logic circuits or circuit modules within thecomputing system. The implementation is a matter of choice dependent onthe performance and other requirements of the computing system.Accordingly, the logical operations described herein are referred tovariously as states, operations, structural devices, acts, or modules.These operations, structural devices, acts, and modules may beimplemented in software, in firmware, in special purpose digital logic,and any combination thereof

The method 200 is described from the perspective of the base station108. As such, the method 200 is described with additional reference toFIG. 1. The method 200 begins and proceeds to operation 202, where thebase station 108 collects the local signaling load information 106. Thelocal signaling load information 106 can include signaling utilizationinformation associated with the utilization of signaling resourcesavailable to the base station 108. In some embodiments, the base station108 collects signaling utilization information, and then calculates acomposite signaling load level of the base station 108 for inclusion inthe cell broadcast message 104. A composite signaling load level can becalculated utilizing any signaling load calculation method, which, forexample, may be selected by or for a service provider operating the basestation 108 based upon the needs of the service provider.

From operation 202, the method 200 proceeds to operation 204, where thebase station 108 learns the signaling load information 112 from one ormore neighbor base stations, which may include one or more of the otherbase stations 114, that operate within the same RAN. In someembodiments, the base station 108 learns the signaling load information112 utilizing a self-organizing network or self-optimizing networkfeature such as provided by 3^(rd) Generation Partnership Project(“3GPP”) and/or New Generation Mobile Networks (“NGMN”). In particular,the base station 108 can utilize the Automatic Neighbor Relation (“ANR”)detection feature of LTE to detect one or more of the other basestations 114 and collect the signaling load information 112 therefrom.Other mechanisms by which the base station 108 can learn signaling loadinformation of one or more neighboring cells are contemplated.

From operation 204, the method 200 proceeds to operation 206, where thebase station 108 learns the signaling load information 112 of one ormore overlapping cells that may include one or more of the other cells116 in which one or more of the other base stations 114 operate, andthat utilize a different RAT than the RAT utilized by the base station108. For example, the base station 108 and one or more of the other basestations 114 may operate in accordance with different RATs, and may alsooverlap in radio range such that the base station 108 is capable ofreceiving signals broadcast by one or more of the other base stations114. In such a configuration, the base station 108 can learn thesignaling load information 112 from the other base stations 114 andutilize the information to enhance the collective signaling loadinformation provided to the mobile device 102 in the cell broadcastmessage 104.

From operation 206, the method 200 proceeds to operation 208, where thebase station 108 learns the signaling load information 112 of one ormore overlapping cells that may include one or more of the other cells116 in which one or more of the other base stations 114 operate, andthat utilize a different frequency than the frequency utilized by thebase station 108. For example, the base station 108 and one or more ofthe other base stations 114 may operate in accordance with differentradio frequencies, and may also overlap in radio range such that thebase station 108 is capable of receiving signals broadcast by one ormore of the other base stations 114. In such a configuration, the basestation 108 can learn the signaling load information 112 from the otherbase stations 114 and utilize the signaling load information 112 toenhance the collective signaling load information provided to the mobiledevice 102 in the cell broadcast message 104.

From operation 208, the method 200 proceeds to operation 210, where thebase station 108 generates the cell broadcast message 104 including atleast a portion of the local signaling load information 106 and/or thesignaling load information 112, collected at operations 202-208. Fromoperation 210, the method 200 proceeds to operation 212, where the basestation 108 sends the cell broadcast message 104 to one or more mobiledevices, including the mobile device 102. From operation 212, the method200 proceeds to operation 214, where the method 200 may end.

Although the method 200 is described as being performed for one basestation, in some implementations, the method 200 is utilized by aplurality of base stations operating in the same RAN and/or acrossmultiple RANs that may utilize the same or different RAT and/or the sameor different radio frequency. Accordingly, in these implementations,mobile devices operating within various RANs can receive one or morecell broadcast messages that provide insight into the signaling loadconditions of the various RANs to which the mobile devices are capableof connecting. For cases in which a single cell broadcast message isutilized, network signaling load information of one or more cells can beconcatenated within the same message. The mobile devices can thenutilize this information at least in part to select one or more of theRANs and connect to the select RANs.

In some embodiments, signaling load information is sent in an order ofpriority based upon, for example, signaling load conditions and/or otherfactors, such as, but not limited to, RAT, frequency band, and carrierpreferences. The priority order can convey to a mobile device thepreference of RAT, frequency band, and/or cellular network the mobiledevice should select. If a single cell broadcast message is used,signaling load information can be concatenated and listed within thecell broadcast message in an order of priority.

Turning now to FIG. 3, a flow diagram illustrating aspects of a method300 for utilizing signaling load information received in a cellbroadcast message, such as the cell broadcast message 104, to select aRAN will be described, according to an illustrative embodiment. Themethod 300 is described from the perspective of the mobile device 102.As such, the method 300 is described with additional reference to FIG.1.

The method 300 begins and proceeds to operation 302, where the mobiledevice 102 receives the cell broadcast message 104 from the base station108. The cell broadcast message 104 can include at least a portion ofthe local signaling load information 106 and/or the signaling loadinformation 112 collected at operations 202-208 of the method 200,described above. From operation 302, the method 300 proceeds tooperation 304, where the mobile device 102 executes the network decisionengine 122 to select a RAN based in part upon the signaling loadinformation included in the cell broadcast message 104. In someembodiments, the network decision engine 122 factors one or morepolicies and/or one or more user profiles for a user of the mobiledevice 102 in selecting one or more RANs. From operation 304, the method300 proceeds to operation 306, wherein the mobile device 102 connects tothe selected RAN. From operation 306, the method 300 proceeds tooperation 308, wherein the method 300 may end.

In some embodiments, signaling load information is received by a mobiledevice in an order of priority based upon, for example, signaling loadconditions and/or other factors, such as, but not limited to, RAT,frequency band, and carrier preferences. The mobile device can utilizethe priority order to determine a preference of RAT, frequency band,and/or cellular network of a carrier providing service to the mobiledevice and based the selection of RAN at least in part upon thispreference.

Turning now to FIG. 4, aspects of an illustrative operating environment400 for various concepts disclosed herein will be described. It shouldbe understood that the operating environment 400 and the variouscomponents thereof have been greatly simplified for purposes ofdiscussion. Accordingly, additional or alternative components of theoperating environment 400 can be made available without departing fromthe embodiments described herein.

The operating environment 400 shown in FIG. 4 includes the mobile device102, which is described above in greater detail with reference toFIG. 1. In the operating environment 400, the mobile device 102 isconfigured to connect to and communicate with a RAN 402. The RAN 402 canoperate in accordance with any of the technologies described hereinabove. In the illustrated embodiment, the RAN 402 includes anSIB-incompatible base station 404. The SIB-incompatible base station 404does not support SIBs that include signaling load information(hereinafter “signaling load-based SIB”). In such instances, the mobiledevice 102, and more particularly, the network decision engine 122, cangenerate a signaling load query 406 and send the signaling load query406 to a network signaling load management system 408. In response, thenetwork signaling load management system 408 can obtain the signalingload information requested in the signaling load query 406 from asignaling load information database 410 and provide the requestedsignaling load information to the mobile device 102 in a signaling loadquery response 412 (“signaling load response 412”).

The network signaling load management system 408 receives signaling loadinformation from the RAN 402 and stores the signaling load informationin the signaling load information database 410. The signaling loadinformation can include any of the various types of signaling loadinformation described above. The network signaling load managementsystem 408, in some embodiments, requests signaling load informationfrom the RAN 402 and, more particularly, one or more network elementsoperating within the RAN 402 such as the SIB-incompatible base station404. As such, the network signaling load management system 408 can be ina pull configuration with one or more network elements of the RAN 402.In some other embodiments, the network signaling load management system408 receives the signaling load information pushed by one or morenetwork elements of the RAN 402. Although the network signaling loadmanagement system 408 is illustrated as being external to the RAN 402,the network signaling load management system 408 can operate within theRAN 402 or elsewhere within a mobile telecommunications network thatincludes the RAN 402.

Although the network signaling load management system 408 is illustratedas being in communication with a single RAN, the network signaling loadmanagement system 408 may be in communication with any number of RANs toreceive signaling load information therefrom. Moreover, the signalingload information received from the RAN 402 can include signaling loadinformation for one or more other RANs that operate in accordance withother technologies and/or frequencies.

The mobile device 102 can generate the signaling load query 406 on aperiodic basis, which may be pre-defined, for example, by a serviceprovider operating the RAN 402 and provided to the mobile device 102. Insome embodiments, the signaling load query 406 is sent more or lessfrequently based upon the performance characteristics of the currentserved technology provided via the RAN 402, the performance of theservice provider that operates the RAN 402, and/or the performance ofone or more layers of a mobile telecommunications network that includesthe RAN 402.

In some embodiments, the mobile device 102 generates the signaling loadquery 406 including the served physical cell ID (“PCI”) for the cell towhich the mobile device 102 is connected, and/or the cell ID in thesignaling load query 406. In these embodiments, the network signalingload management system 408 can send the corresponding signaling loadinformation to the mobile device 102 and one or more neighboring cells.In this manner, load balancing works in the presence or absence of radiotechnologies/base stations with signaling load-based SIB support.

From operation 502,the method 500 proceeds to operation 504, where the mobile device 102sends the signaling load query 406 to the network signaling loadmanagement system 408. From operation 504, the method 500 proceeds tooperation 506, where the mobile device 102 receives the signaling loadresponse 412 from the network signaling load management system 408. Fromoperation 506, the method 500 proceeds to operation 508, where themobile device 102 selects a RAN based in part upon the signaling loadinformation included in the signaling load query response 412. Fromoperation 508, the method 500 proceeds to operation 510, where themobile device 102 connects to the selected RAN. From operation 510, themethod 500 proceeds to operation 512, wherein the method 500 may end.

The method 600 is described with additionalreference to FIG. 4. The method 600 also is described from theperspective of the network signaling load management system 408.

The method 600 begins and proceeds to operation 602, where the networksignaling load management system 408 receives the signaling load query406 from the mobile device 102. From operation 602, the method 600proceeds to operation 604, where the network signaling load managementsystem 408 analyzes the signaling load query 406 to determine signalingload information to include in the signaling load response 412. Fromoperation 604, the method 600 proceeds to operation 606, where thenetwork signaling load management system 408 obtains the requestedsignaling load information from the signaling load information database410.

From operation 606, the method 600 proceeds to operation 608, where thenetwork signaling load management system 408 generates the signalingload response 412 that includes the signaling load information obtainedfrom the signaling load information database 410 at operation 606. Fromoperation 608, the method 600 proceeds to operation 610, where thenetwork signaling load management system 408 sends the signaling loadresponse 412 to the mobile device 102. From operation 610, the method600 proceeds to operation 612, where the method 600 may end.
